6 Claims. l

The present invention pertains to a novel goal and resides in improvements on my United States Patent No. 2,449,708 of September 21, 1948.

In the patented device the end posts of the goal yield under impact by buckling at the center. More yieldability at the bottom of the posts is desirable, and the principa1 object of the invention is to fill this need. Other features of the patented goal may be incorporated although not shown herein.

The stated object is accomplished by mounting the upper ends of the posts pivotally on the xed frame structure and setting the lower ends slidably in a pair of fixed braces. These ends are backed by springs which are compressed as the ends are displaced.

In order to prevent too rapid a return of the posts, each is connected to a check device or dash pot including a fluid-filled cylinder and a bypassing piston, The posts are further backed by articulated props which guide their movement. The props are also fitted with checks or dash pots of the character set forth.

The invention is fully disclosed by way of eX- ample in the following description and in the accompanying drawings in which:

Figure l is a prespective view of the goal;

Figure 2 is a detail transverse vertical section, and

Figure 3 is an end View showing in dotted lines the deflected position.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

As in the aforementioned patent, the base of the goal consists of two arcuate sections I joined together at one end, with their remaining ends spaced apart the distance of the desired goal entrance. A center post 2 is secured to the connection of the sections I and stands somewhat rearward of a line joining the free ends of the sections I. From each such end, a tubular brace 3 extends inwardly and is Xed to the corresponding section in the manner of a chord. The braces are preferably perpendicular to a line joining the free ends of the sections I.

Each brace 3 is formed with a longitudinal slot 4 forming its forward end. In each slot is slidably mounted the lower end of a side post 5. For this purpose the lower end of each post is formed with a ball 6 over which is a restriction 'I receivable in the slot by sliding the ball in the open end of the section I. After this the open end is plugged at 8.

The upper ends of the posts are joined by a bar 9. 'I'he center post 2 is inclined for attachment to the bar 9 at I0. Arcuate sections II, of less depth than the sections I, are fastened to the ends of the posts 5 and 2. The four arcuate sections and the three posts form a frame on which is mounted the screen I2 in two somewhat conical surfaces.

On each brace 3 is mounted a closed cylinder I3 containing a iiuid and a ported or by-passing piston I4. A rod I5 extends from the piston and is pivoted to the corresponding post 5 by a strap I6. Each ball Ii is backed by a coil spring I'I in the brace 3 and bearing against a pin or stop I8.

It is now evident that the lower end of each post 5 will move in the brace 3 under impact. I-ts return movement by the compressed spring I'I will be checked by the retarded return of the by-passing piston I4, after the fashion of a door check. The cylinder I3 and piston I4 will therefore be identified in the claims as a check.

To each brace 3 is pivotally attached the lower end of a link I 9, at 20, behind the cylinder I3. The upper end of the link is joined to the corresponding post 5, forming an articulated prop. The connection consists of a rod 2I. The upper end of link I9 is also connected to brace 3 by a rod 2l pivoted to the upper end of the link I9 and carrying a by-passing piston 22 working in a uid-lled cylinder 23, pivoted at 24 on the brace 3, The cylinder is surrounded by a coil spring 25 having its ends connected respectively to the cylinder and the link I9.

It has already been pointed out that either post 5 Will yield at its lower end on impact by a player. In this movement, the upper end of the post swivels on the top bar I0, to which it is pivotally attached. The movement of the posts is guided by the articulated props 2I-23, and the accompanying rearward movement of each link I9 is restrained by expansion of its spring 25 and the check 22, 23. When the spring recoils, the return of the post is further retarded or cushioned by the check 22, 23 as in the case of the checks I3, I4.

It is now evident that injury to the players by impact with the posts 5 is practically eliminated by the yieldable mounting of the posts as described.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without de- -parting from the scope of the invention as indicated by the appended claims.
